Using Empirical Research Evidence, Explain the Effects

Using empirical research evidence, explain the effects of one and only(a) neurotransmitter on human behavior. Neurotransmitters are chemical messengers, which send signals and communicate data through neurons (nerve cells), cells, our dispositions and our bodies. Neurotransmitters are egressd and travel through terminals in the brain until they pass received receptors. Neurotransmitters and their functions are located and carried out in various sections of the brain. It uses neurotransmitters to call for your body carry out certain functions, such as devising your heart beat and your lungs breathe.Scientists are not sure of how many neurotransmitters genuinely exist, but they can be sorted into two main different types. These are called exitatory neurotransmitters and repressive neurotransmitters. Exitatory neurotransmitters stimulate different pause of the brain. Three wellknown types of exitatory neurotransmitters are dopamine, norepinephrine, epinephrine. Inhibitory n eurotransmitters calm the brain and create balance. Three different types of inhibitory neurotransmitters are serotonin, gaba and dopamine.Although dopamine was already mentioned as an exitatory neurotransmitter, it is special because it is considered to be both exitatory and inhibitory. Dopamine actuates the 5 different dopamine receptors dopamine 1 (D1), dopamine 2 (D2), dopamine 3 (D3), dopamine 4 (D4) and dopamine 5 (D5), and helps to control parts of the brain that react to pleasure and reward. It helps the brain not only to see rewards, but to motivate a individual to suffer those rewards, or at least try to move towards them. It in addition helps to motivate humans to perform the actions again, to acquire the same rewards.This involves activities such as eating, sex, and other such activities that create a rush of adrenaline. Along with that, dopamine overly helps the body to move and have emotional responses to certain objects or situations. A lack of the dopamine neuro transmitter can have a return of negative effects, one main illness being Parkinsons disease. Also, lot that are low in or lacking in dopamine activity are more likely to have addictions or go chemical dependent. When dopamine is not produced correctly in the frontal lobe of the brain, attention, focus, storage and the ability to analyse can all be negatively effected.The dopamine neurotransmitter can also effect people socially. Studies have shown that anxiety in social situations and a lack of dopamine 2 receptors can genuinely often be link, also, people with bipolar disorder are precondition drugs known as anti-psychotics, which block dopamine, in an aim to reduce mania. A essay was carried out on May the 2nd and was published in the Journal of Neuroscience. The scientists that worked on the study included a team of Vanderbilt University scientists, medical specialty student Michael Treadway and professor of psychology, David Zald.The aim of the experiment, was to test whether ambitious and hard work go getters in the workplace, who were willing and able to work hard to obtain the reward they want, had a different level of dopamine write out in the brain (or certain parts of the brain), than workers that tended to slack off more and were little willing to work towards obtaining a reward. The team of scientists utilise a positron emission tomography (or PET scan), which is a medical imaging technique, used to produce 3D images of functions taking place in the brain, and other parts of the body.The scientists discovered that the ambitious workers, working towards a reward, had a larger release of the dopamine neurotransmitter in the parts of the brain that, studies have shown, are cerebrate to motivation and obtaining reward. These parts of the brain are called the striatum and the ventromedial prefrontal cortex. not only did they find out this, but they also uncovered that little(prenominal) motivated people in the workplace had a high releas e of dopamine also, but in a completely different part of the brain. This dopamine release was happening in the anterior insula of the brain, which is the section that is linked to emotion and risk perception.Many different types of studies have proven that dopamine affects press release after rewards, and motivation in the brain, but the speciality of this particular study is that it proves that dopamine is not only linked to rewards in hardworkers, but also can be linked to emotions and risk perception in less ambitious workers. This empirical research study clearly shows that dopamine has an affect on human behaviour by effecting the ambition, or lack of it, in the workplace when it comes to working towards reaching a goal and obtaining a certain reward.
